Distributor sticking in block, can't adjust timing

Post  JBR-3 on March 1st 2018, 3:40 pm

I've had this happen now on a couple of engines, big and small blocks. Can't rotate the distributor, can barely pull it out altogether.

Now I know it has to be a pretty close fit to hold the gear in proper mesh with the cam gear.

Anybody have a trick to share ? Just periodically pull it and re-lube  the distributor case with antisieze ?

No vacuum pumps on these engines.

I've battled this and haven't had much success; pb blaster helps if it is clean.

I have used a large pipe wrench with heat and wax on some to get it free.
Sometimes, it will destroy the distributor.

The engine may not require frequent timing adjustments, but it might help to turn that distributor and reset the timing occasionally....just because. And a shot of penetrating oil once in a while might head off the problem even if you're not making an adjustment at that time. I hate tearing up parts just because I ignored them for a while.

Check the bore diameter. According to Ford's blueprint the bore dia, should be 1.5595/1.5610

I have never measured the specs but when it starts to get sticky I take it out and just clean up the distributor with some emery cloth then grease the o-ring area. Of course if it's already seized then it's too late for this method.

I have noticed on a rebuilt engine that I sprayed paint on without covering up the hole good,I know halfass, it would be stuck. My 400 is stuck and will not turn,it's cracked from prizing on the vacuum advance. It was definitely a halfass painted when rebuilt. Laughing
